For me FF in current state absolutly unusable. You can load one-two sites and then crashes heavy :)

Realted to OWB , there is nothing what we can change. Joerg say pretty clear, that he will not add anything to OWB, because if was designed not for desktop browser :) Only if anyone else will start to works on it, or maybe someone will port Fab's OWB from MorphOS. But its indeed sad .. OWB on OS4 in current stage are very cool. Sadly if it will dead-end :(
